dt: Move device tree documentation out of powerpc directory

The device tree is used by more than just PowerPC.  Make the documentation
directory available to all.

v2: reorganized files while moving to create arch and driver specific
    directories.

-MPC5121 PSC Device Tree Bindings
-
-PSC in UART mode
-----------------
-
-For PSC in UART mode the needed PSC serial devices
-are specified by fsl,mpc5121-psc-uart nodes in the
-fsl,mpc5121-immr SoC node. Additionally the PSC FIFO
-Controller node fsl,mpc5121-psc-fifo is requered there:
-
-fsl,mpc5121-psc-uart nodes
---------------------------
-
-Required properties :
- - compatible : Should contain "fsl,mpc5121-psc-uart" and "fsl,mpc5121-psc"
- - cell-index : Index of the PSC in hardware
- - reg : Offset and length of the register set for the PSC device
- - interrupts : <a b> where a is the interrupt number of the
-   PSC FIFO Controller and b is a field that represents an
-   encoding of the sense and level information for the interrupt.
- - interrupt-parent : the phandle for the interrupt controller that
-   services interrupts for this device.
-
-Recommended properties :
- - fsl,rx-fifo-size : the size of the RX fifo slice (a multiple of 4)
- - fsl,tx-fifo-size : the size of the TX fifo slice (a multiple of 4)

-Example for a board using PSC0 and PSC1 devices in serial mode:
-
-serial@11000 {
-	compatible = "fsl,mpc5121-psc-uart", "fsl,mpc5121-psc";
-	cell-index = <0>;
-	reg = <0x11000 0x100>;
-	interrupts = <40 0x8>;
-	interrupt-parent = < &ipic >;
-	fsl,rx-fifo-size = <16>;
-	fsl,tx-fifo-size = <16>;
-};
-
-serial@11100 {
-	compatible = "fsl,mpc5121-psc-uart", "fsl,mpc5121-psc";
-	cell-index = <1>;
-	reg = <0x11100 0x100>;
-	interrupts = <40 0x8>;
-	interrupt-parent = < &ipic >;
-	fsl,rx-fifo-size = <16>;
-	fsl,tx-fifo-size = <16>;
-};
-
-pscfifo@11f00 {
-	compatible = "fsl,mpc5121-psc-fifo";
-	reg = <0x11f00 0x100>;
-	interrupts = <40 0x8>;
-	interrupt-parent = < &ipic >;
-};
